Show my anything from a professional source that warns of any DANGER of sickness by drinking the way the normal majority does, without any conscious intent.
I can't provide professional sources, but I can provide a 100% trustable anecdote. (hey, it's the internet, you get what you pay for)
I know someone who used to drink water when they felt thirsty. Over a 4-5 year period, this person suffered from no fewer than 4 bladder infections, 3 of which required visits to the emergency room. Since then (10+ years), they have made an effort to drink more water than the minimum necessary to feel well, and not a single infection.
This doesn't necessarily mean this person needs special treatment - a day with low water intake will probably not hurt - but let's not paint everyone with the same brush.
